Jeffrey G. Rau

I’m an associate professor at the University of Windsor specializing in theoretical condensed matter physics.

My research is primarily in quantum magnetism with some connections to strongly correlated systems more broadly. I study how frustration, many-body effects and quantum mechanics can produce emergent behaviour in real materials. Recent areas of focus include order-by-disorder, altermagnetism, spin dynamics, and frustration in anisotropic systems.

Previously, I did post-doctoral research at the Max Planck Institute for the Physics of Complex Systems and the University of Waterloo. I received my Ph.D. from the University of Toronto and my undergraduate degree from the University of Windsor.
